How do i find what a company paid me in 2019 ..i have quickbooks on line

Welcome to the Community, @genekuber.

We want to help you with your question about the payments. However, we need some clarification about it to get this sorted as quickly as possible and to provide you with the right resolution.

Are you referring to the payments coming from a specific customer? If yes, I recommend running the Transaction List by Customer report and filter to show customer payments only.

Here's how:

1. On the left panel, click Reports.
2. Under Sales and customers, select Transaction List by Customer.
3. Press Customize.
4. Change the report period.
5. Below Filter, choose a specific customer and transaction types you want to show. 
6. Hit Run report. 

Meanwhile, I've attached some articles you can visit to learn more about the reports, like how you can customize them further in QuickBooks:

• Run reports in QuickBooks Online

I appreciate you for taking the time to visit us here today, and I look forward to your response.
